MOSTLY AI provides a synthetic data platform for high-fidelity, privacy-safe tabular data. It ships an open-source Python SDK (mostlyai, Apache 2.0) that runs in LOCAL mode for on-prem training or CLIENT mode against the hosted MOSTLY AI Platform, plus a REST API used by both the SDK and the web app. The SDK is powered by the TabularARGN model architecture and supports differential privacy.
